Technical specs

General performance parameters such as number of shaders, GPU core base clock and boost clock speeds, manufacturing process, texturing and calculation speed. These parameters indirectly speak of performance, but for precise assessment you have to consider their benchmark and gaming test results. Note that power consumption of some graphics cards can well exceed their nominal TDP, especially when overclocked.

Pipelines / CUDA cores	4608	6912
Core clock speed	1825 MHz	1410 MHz
Boost clock speed	2250 MHz	1410 MHz
Number of transistors	26,800 million	54,200 million
Manufacturing process technology	7 nm	7 nm
Thermal design power (TDP)	300 Watt	400 Watt
Texture fill rate	648.0	609.1

Compatibility, dimensions and requirements

Information on compatibility with other computer components. Useful when choosing a future computer configuration or upgrading an existing one. For desktop video cards it's interface and bus (motherboard compatibility), additional power connectors (power supply compatibility).

Interface	PCIe 4.0 x16	PCIe 4.0 x16
Length	267 mm	no data
Width	2-slot	IGP
Supplementary power connectors	2x 8-pin	None

Memory

Parameters of memory installed: its type, size, bus, clock and resulting bandwidth. Note that GPUs integrated into processors have no dedicated VRAM and use a shared part of system RAM.

Memory type	GDDR6	HBM2e
Maximum RAM amount	16 GB	80 GB
Memory bus width	256 Bit	5120 Bit
Memory clock speed	16000 MHz	3.2 GB/s
Memory bandwidth	512.0 GB/s	2,039 GB/s
Shared memory	-	no data

Video outputs and ports

Types and number of video connectors present on the reviewed GPUs. As a rule, data in this section is precise only for desktop reference ones (so-called Founders Edition for NVIDIA chips). OEM manufacturers may change the number and type of output ports, while for notebook cards availability of certain video outputs ports depends on the laptop model rather than on the card itself.

Display Connectors	1x HDMI, 2x DisplayPort, 1x USB Type-C	No outputs
HDMI	+	no data

API support

APIs supported, including particular versions of those APIs.

DirectX	12 Ultimate (12_2)	N/A
Shader Model	6.5	N/A
OpenGL	4.6	N/A
OpenCL	2.0	2.0
Vulkan	1.2	N/A
CUDA	no data	8.0
